GASEOUS-FUEL MIXER.

Specification of Letters Patent.

Patented sent. 31 191 ft Application filed June 11, 3913. Serial No. 772,932.

To all 1.071 out it may concern Be it known that I, WILLIS S. PARKER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Gaseous-Fuel Mixers, of which the following is a specification.

My invention relates to gaseous fuel mixers and it relates more particularly to an improved form of device adapted to be inserted in theintake pipe of a gaseous fuel engine between the carburetor and the suc tion chamber of the engine.

The principal object of my invention is to provide a simple, inexpensive, and eliicient device for thoroughly co-mingling the hydrocarbon fuel vapor with the air and wvhich will insure .the' complete evaporation of the fuel.

My invention contemplates the employmeuthof two frusto-conical screens or sieves forming an annular space therebetween, and

the provision of means for inducing a whirl-' ing motion in the passing fuel and air mixture within said annular space and against the roughened surfaces of the sieves or screens for the purpose above set forth.

The nature and characteristic features of my invention willbe more readily under stood from the following description taken in connection with the accompanying drawings forming a part hereof, in which- Figure l is a side elevation, partly in section, of a carburetor and a portion of the intake pipe of the engine, with a device cmbc-dying the main features of my present invention shown mounted in operative position therein; Fig. 2 is-a side elevation, en-.

larged, showing the external appearance of the device of my invention, detached; Fig. 3 is a vertical central section thereof; and Fig. 4 is a horizontal section thereof taken. on the line rvc of Fig. 3.

Referring to [the drawings, in the particular embodiment of my invention therein which forms a continuation of the intake pipe or conduit to the engineL i is a circular ring,'U shaped in cross section as shown in Fig. 3, adapted to form means for mounting the device of my in vention in the intake pipe or conduit, and incidentally adapted to form a gasket between the flanges 6 and 5 above referred to which form the joint between the pipes 2 and 3. Mounted and clamped between the upper and lower portions 8 and 9 respectively of the ring or gasket 4- is a flange-like extension 7* of an annular screen or sieve 7 preferably frusto-conical in shape which extends upwardlyand which, on account of its frustoconical'shape, forms a tapered annular space between its outer surface and the interior surface of pipe 3. The screen is bent over at the top and thence extends downwardly to provide another annular screen or sieve 1}, also preferably frusto-conical in shape and arranged within the screen 7, to form a tapered annular space between the sieve l1 and the upper portion of the sieve 7. A

at the lower end of the frusto-conical sieve ll, so that all the mixture of fuel and air passing through the conduit is constrained to pass between the meshes of some portion of the sieve structure above described.

. Mounted beneath the horizontal screen or sieve-13 in any suitable manner is a stationary winged member 12 the vanes or wings of which are inclined similar to the vanes of rotary fan impellers, whereby the mixture of fuel. and air will be cause to travel with a whirling motion, the principal portion of said mixture passing within the annular space between the sieve structure 11 and the outer sieve structure 3' whereby unevaporated fuel globules will be deposited upon one of the sieve or screen surfaces and evap orated therefrom by the passing nine-rid whereby the mixture will be caused to im-. pinge against the roughened surfaces of the screens and will be thoroughly. 'intermingled and a more uniform and perfect mixture obtained. The winged member 12 may be mounted within the interior of the screen 7 in any suitable manner, such for example as shown in the drawings, that is by providing a dished screen or sieve 10 which extends upwardly within the interior of screen 7 and thereby forms a support to which the winged characteristic features of my invention what member 12 may be secured. The sieve or screen 10- may also be provided with a flange-like extension 1O which may also be clamped between the upper portion 8 and lower portion 9 of the clamping ring 4.

It will be seen thatthere is thus provided a simple'and efficient device for insuring a thorough eaaporation; of the gaseous fuel and r securing a 'uniform mixture of the S .itll. the air, which device is character ig fbwhe provisionof the annular spaces between the two frusto-comcal sieve mem- .bers,withimwhich the mixture is projected witha whirling motion. The arrangement of the ,frusto-conical sieves results in a maximum of evaporating surface and at the same time permits the mixture to freely pass while being subjected to thed'esired manipulation for the'pur os'es set forth;

Having thus escribed the nature and I claim as new and desire to secure by Letters Patent is as follows 1: 'Irrfdevice of the character described, a'pair of annular sieves arranged one within the other and forming an annular space therebetween, anda stationary member mounted beneath said space having a plurallty of inclined vanes adapted to impart a mixture.

whirling motion to a passing vapor and air 2. In a device of the character described adap ed to be mounted in a conduit, a frustocom 1 sieve, another frusto-conical sieve mounted within the first named sieve and forminga tapered annular space in conjunction therewith, and means for imparting a {whirling motion to gaseous mixtures passing through the eondui 3. In a devlce of the character described nesses,

adapted to bemounted in a conduit, a frustoconical sieve, another frusto conical sieve mounted within the first named sieve and mounted within the first named sieve, a stati onary member mounted beneath the second mentioned sieve and having a plurality of inclined vanes adapted to impart a whirling motion to gaseous. mixtures passingthrough the conduit, and another sieve upon whichsaid stationary member is mount ed.-

5. In a device of the character described adapted to be mounted in a conduit, a frustoconical sieve, another frusto-conical sieve mounted within the first named sieve, a sta-.

tionary member mounted beneath the second mentloned sieve and havlng a plurality of inclined vanes adapted to imparta whirling motion to gaseous mixtures passing through the conduit, another sieve upon \vhlch said stationarv member is mounted, the first named sieve and the last named'sieve each having a flange-likeextension, and a sup porting ring U shaped in cross section within which said extensions, are clamped.

In testimony whereof, I have hereunto signed my name in-the presence of two wit- WILLIS S; PARKER. Witnesses:
